Maybe you could try searching the D22 sections for mods to get an idea rather than having everyone give you a list of their mods, that way you can decide what is sweet and what isn't.
G'day im new here (first post) i couldnt recommend more the guys at snake racing for suspension mods and just down right helpful when you ask questions i bought a lift kit off them and my nav drives and handles on and off road 100% better plus i added a chip and boost control valve which gave it a bit more punch and torque...
hope this helps you cheers
